System Architecture

I am pretty happy with manually searching Google and Bing for APIs across different spaces. The more APIs I add to my APIs.json index of APIs, the more words that appear as tags. So I regularly scroll through the list clicking on different keywords to see what comes up in the top 10 search results. I will be manually doing this on a regular basis, but I am looking to see what I can automate as well, so I wanted to see what the first couple of steps I could take to automate this recurring activity.

Some time over a decade ago, the arrival of inexpensive PCB fabrication revolutionised the creation of custom electronics on a budget. It’s now normal for even the smallest projects we featur…

Using cloud resources more conservatively not only saves money but also resources. Check out this episode of The New Stack Makers for more.

Complexity stems from the way a system is subdivided into modules.

As I’m sure many of you know, x86 architecture has been around for quite some time. It has its roots in Intel’s early 8086 processor, the first in the family. Indeed, even the original …

CXL technology has been pushed into the backseat by the Nvidia GTC AI circus, yet Nvidia’s GPUs are costly and limited in supply.

In this article I will discuss what binary serialization is and the difference between that and a more typical JSON or XML serialization.

Leverage Diagrams as Code tools like PlantUML for creating clear, visual representations of complex systems and workflows in cloud…

Address people's biggest concern about formal methods

Explore the pivotal roles of WebSockets, Server-Sent Events, Long-Polling, WebRTC, and WebTransport in shaping real-time web apps. Dive into their unique advantages, limitations, and optimal use cases for informed development choices.

There was considerable attention around Passkeys last year. It was sometimes presented as the password killer technology. This came from the announcements of Apple and Google to support this techno…

Easily identify Hyperledger distributed ledger technologies, understand their differences, and how you want to use them.

A blockchain framework implementation intended as a foundation for developing applications or solutions with a modular architecture.

Understand better how HTTP works in each version.

A look at why ScyllaDB completely bypasses the Linux cache during reads and uses its own efficient row-based integrated internal cache instead.

Our fancy WireGuard setup was accumulating stale peers. Here's what we did about it.

Today, we’re open sourcing Ozone, a tool that lets a team of moderators or curators collaboratively review reports, create labels, and inspect content on the atproto network. Later this week, we’re opening up the ability for users to run their own independent moderation services.

The pidfd abstraction is a Linux-specific way of referring to processes that avoids the race conditions inherent in Unix process ID numbers. Since a pidfd is a file descriptor, it needs a filesystem to implement the usual operations performed on files. As the use of pidfds has grown, they have stressed the limits of the simple filesystem that was created for them. Christian Brauner has created a new filesystem for pidfds that seems likely to debut in the 6.9 kernel, but it ran into a little bump along the way, demonstrating that things you cannot see can still hurt you.

Technical details on how Stripe built Ledger, a state-of-the-art money movement tracking system, including how teams at Stripe interact with the data quality metrics that underlie our payment processing network.

DBOS Cloud is a transactional serverless platform that provides fault-tolerance, statefulness, observability, and cyber-resilience to TypeScript applications. Powered by the DBOS cloud-native OS.

When is a Markov chain useful for solving problems? When you want to model something that's in discrete states, writes David Eastman.

Nix and Guix are a pair of unusual package managers based on the idea of declarative configurations. Their associated Linux distributions — NixOS and the Guix System — take the idea further by allowing users to define a single centralized configuration describing the state of the entire system. Both have been previously mentioned on LWN, but not covered extensively. They offer different takes on the central idea of treating packages like immutable values.
